phylogenomic tree

Frogs invest in cognitive capacity to avoid predators—up until there are too many hungry snakes around for the evolutionary strategy to pay off.

A new study using fairly complete genetic datasets of two phyla of small suspension feeders (Ectoprocta and Entoprocta) reopens the debate on the phylogenetic relationships between them and other animals.

The Scientist spoke with Ohio State University microbiologist Matthew Sullivan about a recent expedition that identified thousands of RNA viruses from water samples and cataloged them into novel phylogenic groups.

The first chromosome-level genome assembly for a ctenophore may allow scientists to finally resolve the roots of the animal family tree.

Phylogenomics data place the enigmatic plankton in the middle of the algal family tree, despite their apparent lack of plastids—an organelle characteristic of all other algae.

The first phylogenomic tree of these insects shows their diversification occurred after they split into Old and New World groups.
